Project description:Exploration of proteome differences between CD45+ and CD45- cell types in renal cell carcinoma tumors and normal adjacent tissue patient samples.
Project description:Maternal helminth infections are a global public health concern and correlate with altered infant immune responses to some childhood immunizations, but a mechanistic understanding of how maternal helminth infection alters the cellular immune responses of offspring is lacking. Here we establish a model of maternal Schistosoma mansoni infection in dual IL-4 reporter mice. We find that offspring born to mothers infected with S. mansoni have impaired production of IL-4 during homoeostasis, and following immunization with a Tetanus-Diphtheria vaccine. Single-cell RNASeq analysis of immunized offspring identified egg antigen-dependent reductions in B-cell cell cycle and proliferation-related genes.
Project description:Side population (SP) cells are highly enriched in stem and progenitor cells. CD45+and CD45- SP cells were found at all developmental lung stages with the highest frequency of cells present at embryonic day 17.5 (E17.5), In order to clarify the role of these cells in lung development, we used oligonucleotide microarrays to evaluate their gene expression profiles. To do this, oligonucleotide gene arrays were performed in triplicate on RNA derived from CD45+ and CD45-SP cells, and CD45+ and CD45- non-SP populations (main population; MP) isolated from the E17.5 lung.

Project description:Analyze and compare the gene expression profile of human bone marrow primary CD45-CD271+ and CD45-CD271- cells. The hypothesis was some genes were differentially expressed in these two populations. Results provided important information regarding the gene expression difference of these two cell populations.
Project description:Critical roles for DNA methylation in embryonic development are well established, but less is known about the roles of DNA methylation during trophoblast development, the extraembryonic lineage that gives rise to the placenta. Here we dissected the role of DNA methylation in trophoblast development by performing mRNA and DNA methylation profiling of Dnmt3a/3b-null trophoblast. We find that most gene deregulation is explained by an erasure of maternal methylation in the oocyte, but partially independent of loss of imprinting of the trophoblast-essential Ascl2 gene. Our results reveal that maternal DNA methylation controls multiple differentiation and physiological processes in trophoblast via both imprinting-dependent and -independent mechanisms. mRNA-seq and WGBS-seq of maternal Dnmt3a/3b-null trophoblast; mRNA-seq of maternal Ascl2 KO trophoblast
